d. Also, specimens of _Sturnira lilium_ and of the
genus _Chiroderma_ from Chihuahua that extend their known ranges
northwestward are reported.

Support for field work that yielded the specimens reported
came from the National Science Foundation, the American
Heart Association, Inc., and the Kansas University Endowment
Association. Catalogue numbers of The University of Kansas
Museum of Natural History are cited. The latitude (N) and
longitude (W) are recorded to the nearest minute for each

~Artibeus lituratus palmarum~ J. A. Allen and Chapman.--Specimens from
Eldorado (24 deg.19', 107 deg.20'), Sinaloa, extend the known range of the
species approximately 265 miles northwestward from Huajimic (21 deg.37',
104 deg.21'), Nayarit. Skins and skulls of 11 specimens (75211-75221, 7
males and 4 females) taken on November 13, 1957, 1 mi. S Eldorado, were
prepared by William L. Cutter. Skeletons of 12 specimens (75222-75233,
3 males and 9 females) from Eldorado were obtained by Cutter on the
same day. None of the 13 females was pregnant. One specimen (75211,
female) is immature; it has open phalangeal ephiphyseal sutures (as do
four other larger individuals); this specimen measured 83 mm. in total
length, weighed 45 grams, and has a skull 26.6 mm. in greatest length,
22.4 mm. in condylocanine length, 13.4 mm. in lambdoidal breadth, and
has unusually small second (last) upper molar teeth, each having about
one half the occlusal area of the M2 of the average adult in the
series. None of the 23 specimens has a third upper molar. All except
one have both third lower molars; one (75233) lacks the third lower
molar on both sides of the jaw. Facial stripes vary from conspicuous to
inconspicuous, but are evident in each of the 11 skins. The two skins
having the darkest pelage are both of males and are the only two skins
having open epiphyseal sutures. Five adult males and three adult
females are represented by skins. Three of the male skins are slightly
darker and less reddish than those of the three females, and the
contrast between paler neck and shoulders and other parts is slightly
less marked. The other two males are paler and more rufous than the
three females; the palest and most rufous of these two males is an old
individual having well-worn teeth. Dichromatism is not correlated with
age or with sex in this series, which, therefore, differs from
specimens reported by Lu
